In a medium bowl, mix flour, flax meal, baking powder, salt and nutritional yeast flakes together. With a fork, blend in margarine until mixture is crumbly. Stir in milk until well blended. Pat dough until 3/4 thick, cut with cookie cutter or top of wine glass and place close together on an ungreased baking sheet. Bake at 450 degrees for 10 - 12 minutes until golden brown on top. Serve hot.
